    *
    * As an example lets assume that
    *
    * - MLocale::translationPaths()
    *   is the list ("/usr/share/l10n/meegotouch", "/usr/share/l10n")
    * - the category is  MLocale::MLcMessages
    * - the name of the locale (returned by mlocale->categoryName(category))
    *   is "en_US"
    * - the base name of the translation file is "foo"
    *
    * then the function will try to load translation catalogs in the following order:
    *
    *   /usr/share/l10n/meegotouch/foo_en_US.qm
    *   /usr/share/l10n/meegotouch/foo_en_US
    *   /usr/share/l10n/meegotouch/foo_en.qm
    *   /usr/share/l10n/meegotouch/foo_en
    *   /usr/share/l10n/foo_en_US.qm
    *   /usr/share/l10n/foo_en_US
    *   /usr/share/l10n/foo_en.qm
    *   /usr/share/l10n/foo_en
    *
    * and return when the first translation catalog was found.
    * If no translation can be found this function returns false.
    *
    * The way locale specific parts are successively cut away from the
    * translation file name is inherited from
    * <a href="http://qt.nokia.com/doc/4.6/qtranslator.html#load">QTranslator::load()</a>
    * because this is used to load the translation files.
    *
    * @param mlocale the locale for which the translations are loaded
    * @param category  this is usually MLocale::MLcMessages but it could
    *                  also be MLocale::MLcTime, MLocale::MLcNumeric,
    *                  etc...
    *
    * @return true if translations could be found, false if not.
